WILLIAM W. KIDENEY, OF CHICAGO, ILLINOIS, ASSIGNOR T0 AMERICAN ELECTRIC COMPANY, OF CHIGAGO, ILLINOIS, A COBPORATIQN OF ILLINOIS.

rnonoemnr To all whom it may concern:

and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Phonographs, of which the following is a specification. My invention relates to an improvement in phonographs, and has for its object means for automaticallycausingthe needle or stylus carried by the sound box to automatically engage the sound record whenthe machine is started in operation and to likewise automatically separate these elements when the machine is stopped.

In prior constructions in which theiieedle has been manually brought into engagement with the sound record there is danger that the record will be scratched or otherwise inj ured owing to improper engagement between the needle and the record. For example in such constructions the needle may be accidentally moved laterally across the record thus materially injuring the same. By my invention, however, I overcome such defects as the needle is brought automatically into proper engagement with the record and thus all danger of scratching or other injury to the record is eliminated.

In the accompanying drawing I have illus trated one embodiment of my invention in which. the table carrying a disk record is automatically raised into a position adjacent to the needle or stylus when the machine is started in operation. I have not illustrated all the details of the phonograph mechanism such as the amplifying horn or box or other auxiliary features as these can beech any. wellknown construction and form no part of mypresent invention. In these drawings I have illustrated merely one form of mechanism for carrying out the .teaturcs of my invention.

Figure 1 is a transverse sectional view of a machine embodying the features ofmy invention;

Fig. 2 is a sectional view taken on the line 22 of Fig. 1;

Fig. 3 is a sectional view taken on the line 33 of Fig. 2; v

Fig. 4 is a detail view of a modified form of weight; and

Fig. 5 is a detailed view on line 5--5 of Fig. 2.

As illustratted, I have shown a suitable "end of the spindle revolves.

inclosing casing 5, to. the cover of which a supporting member 6 is secured. This supporting member is provided with suitable depending brackets for supporting the various parts of the operating mechanism. Thus a bracket 7 is provided for supporting a suitable motor 8. I have shown this motor in the form of an electric motoralthough it will be obvious that other forms of motive power can be employed such as the well known type of spring motor, but for convenience l have illustrated my invention in connection with an electric motor. Power is transu'iitted from this motor to the transmitting shaft 9 which is provided with a worm 10 which meshes with the worm gear 11. This worm gear is mounted on a sleeve 12 in which the operating spindle 13 is .slidably mounted-that is these two members are keyed together in such a manner that the spindle 13 is free to move longitudinallv with respect to the sleeve 12, but no relative rotative movement between these two members is permitted. This spindle passes through an opening in the cover of the inclosing casing and carries on its upper end the revolving table 14 of the usual well known construction, which table supports the disk record. A suitable needle or stylus 39 carried by the sound box 39 is provided, these elements being of any well known or desired construction. This stylus is so mountedwith respect to the record that it is adapted to engage the record only when the table is in raised position as will be hereinafter more fully described.

hiounted on the opposite or lower end of the spindle is a suitable block 15 which contains a socket 16 within which the lower Secured to this block 15 is a yoke member consisting of the arms 17 18which are pivotally mounted on the pin 19 mounted in the depending bracket 20. At their opposite ends these two arms are brought together and a counter weight 21 is pivotally mounted on the same. The movement of this weight is limited, however, by a stop 22, the purpose of which movement will be hereinafter more clearly pointed out. This weight is suflieient to substantially counter-balance the weight of the table 14 and in order to'obtain a proper balance the position. of this weight is rendered adjustable along the arms 17 and 18 by reason of the slot 28 clearly shown Specification of Letters Patent.

In this manner the speed of the operating shaft can be readily adjusted, although other suitable speed adjusting mechanism can be employed without departing from the spirit of my invention.

It will thus be seen that I have devised a very efiicient mechanism for automatically bringing the sound record into operative relation with the stylus. It will be noticed that this mechanism is entirely independent of the driving mcchanismthat is no extra load is placed upon, the driving mechanism by reason of the fact that the table is raised and lowered into operative-position. This feature is of importance as it enables a smaller sized motor to be employed than would be the case where the motive power itself was directly employed to raise and lower the table.

While I have illustrated \YJl described one embodiment of my invention and one in which the revolving table is moved relative to the stylus it is obvious that the stylus could be automatically moved instead of the table without departing from the broader aspects of my invention. Various other changes and modifications can be made without departing from the spirit of my invention.
